Final answer:
The kinetic chain in physics includes the systems of kinematics, dynamics, and energy systems, which together describe the motion, forces, and energy in a system.
Step-by-step explanation:
The three systems that are collectively referred to as the kinetic chain are kinematics, dynamics, and energy systems. Kinematics is the branch of mechanics that describes the motion of points, bodies, and systems of bodies without considering the forces that cause them to move. Dynamics, on the other hand, is concerned with the forces and torques and their effect on motion. Lastly, energy systems in physics refer to the potential, kinetic, and other forms of energy in a system and how they convert from one form to another.
By understanding the concept of the kinetic chain, students can better analyze how forces and motion in one part of the system affect others. In more complex systems, such as those involving multiple objects, it is important to consider the system as a whole when analyzing motion and energy transfers. This holistic approach is crucial for accurately describing the linear motion of a system through displacement, velocity, and acceleration of its center of mass.
